I hate when you are checking out in a store where you need a shopping cart (grocery, Target, etc.) and the person in front of you goes into the checkout lane first pulling their cart in behind them. Then they unload the cart, pay for their items and leave their cart parked right there in the middle of the checkout lane with you stranded all the way at the back of the conveyor belt as they walk out on their merry way.

That happens to me all the time. I've finally started to yell "HEY, you FORGOT something!" at them as they leave. Most of them get embarrassed and pull the cart out but some get snotty and stick their nose up in the air and walk on out.
I hate the pushing of credit cards too. I finally found the best way to stop it. I just tell them all I already have one of their credit cards. It's a lie, I know, but it stops the hassle so nicely
I also hate it when employees working on restocking the shelves all but completely block a display from being shopable and when you ask to move something so you can see what is there they get an attitude like you are putting them out.
To the poster that heard someone at Home Depot use the F word - a couple of weeks ago I heard someone drop the "F bomb" at Chik-fil-a! That is one place you would never expect to hear any vulgar language. I knew the manager so I made sure he knew what was going on behind the counter!
About the subject of cashiers opening new lanes and asking for the next person in line - 9 times out of 10, even though they said next person in line the person all the way at the back of the line makes a beeline for the open register. I've gotten pretty bold about it though - I will stop them and either say "I'm sorry but I was next in line" or "I'm sorry, but I believe this customer here was next in line". When customers try to jump in line at my store when we open a new register, I'll send them back to where they were and tell them we are taking people in order of the line. Funny thing is, it's usually the senior citizens at the end of a line that high tail it to the newly opened register when the cashier calls next in line - where are they going in such a hurry?
